OIL-PUMP..

SPECIFICATION forming part of Letters Patent No. 786,937', dated April 11, 1905.

i Application led July 1l, 1904. Serial No. 216,015.

To @ZZ tell/mrt if; may concer/1.:

Be it known that I, vFLAviUs J. YOUNG, a citizen of theUnited States, residing at Fort ayDe, in the county of Allen, in the State of Indiana, have invented certain new and useful Improvements in Oil-Bumps; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanyingdrawings, which form part of this specilication.

My invention relates to improvements in oil-pumps.

The objeetof my present invention is to provide a cheap, simple, and eliicient selfmeasuring pump for the retailing of illuminating-oils which is convenient in operation and reliable in actionand adapted to indicate to the operator the exact quantity of oil to be delivered to the customer for a stipulated sum, the monetary value of the quantity delivered to a receptaclelof unknown capacity, the quantity of oil delivered at each operation of the pump, and the quantity remaining in the tank or reservoir with which the pump is connected.

My invention consists of an upright supporting-standard carrying the actuating, selfmeasuring, and indicating mechanisms and provided with a dial-plate and graduated scale for the indicating mechanism, a pump-cylinder located in the oil-reservoir and provided witha discharge-pipe, a plunger mounted in the pump-cylinder and connected with the actuating' mechanism.

The principal novel features of my invention reside in the eiiicient cooperation of the actuating, selfmeasuring, and indicating' mechanisms. A

ln the accompanying drawings similar reference-numerals indicate like parts throughout the several views, in which- Figure l isa side elevationof myinvention in operative position upon a proper tank or reservoir shown in vertical section and partly broken away. Fig. Q is a side view of the pump-standard and operating mechanism, taken at right angles to that of Fig. 1 and looking from the left. Fig. 3 is a detail inside side view of one section of the two-part pump-head, showing a portion of the actuating' mechanism. Fig. #l is a detail of the other section of the pump-head, showing the dial and indicating mechanism.

rlhe upright standard l is adapted to be rigidly seeured at its base to the'top of the tank 2 and has upon its upper end a hollow circular two-part head formed of the integral seetion 3 and the detachable section 4:. ln a fixed sleeve 30, which is integral with the head-section l, is rotatably mounted an arbor 19, carrying upon its extended front end an indicator-hand in cooperative relation with the dial-plate 35, detachably mounted in any proper manner upon the front face of the pump-head section 4. On the other extended end of the arbor 19 is lixed the crank Q0, having a lateral lug 23 upon its inner face,adapted in cooperation with the limiting-stops hereinafter described to limit the throw of the said crank. rl`his crank is provided upon its lower end with a handle 21.

The pump-head sections 3 and e, provided with the respective lugs 5 and (i, have vertical openings 9 and l0 for the upper portion of the vertical tube S and the discharge-pipe 7, both of which pass through suitable openings in the extended foot 2' of the standard l and the latter of which has its lower end fixed in the pump-base. The tube S is loosely mounted in the foot Z and has its lower end loosely suspended in the pump-cylinder 14, which is of any proper constructioiuis open at the top, and the bottom has proper feet l5 and an inlet and check-valves. (Not shown.) ln this tube 8 is loosely mounted the plunger or pump-rod ll, to which is secured near its upper end the tube 8 by means of a collar 'l2 and set-screw 13, by means of which the tube 8 and the pump-rod can be adjusted relative to the pump l-l and to each other withoutdisturbing the connection of the driving mechanism therewith, about to be described. Directl y beneath the upper curved end of thedischarge-pipe is arranged a fixed drip-pan 16. which discharges into the tank 2.

On the arbor 19 is iixed a drum 1S, to the perimeter of which is lixed in any proper manner, as at Q5, an actuating-cable 26, hav- IOO ing its opposite ends iixed to the respective adjustable blocks 17 on the tube 8. On the l sleeve 30 are loosely mounted the ratchet register-wlieel 29 and the lever-arm 31, carrying upon its :free end the weighted pawl 32, adapted to engage the said wheel. The drum 13 is provided upon its inner face with a lateral iixed pin 33, adapted to actuate the registerwheel 29 by contact with the adjacent end of the pawl 32 in the manner hereinafter described. rlhe drum 13 has a slot 28, which is coincident with a similar slot 27 in the outer face of the head-section 3, whereby the operator can readily return the wheel 29 toits normal position after each operation thereof in use.

Gn the outer face of the head-section 4 is detachably mounted a dial-plate 35, having a graduated scale thereon, such as would be proper for use when the retail price of oil is twenty cents a gallon. This dial-plate has an opening` 36, through which the number of gallons discharged by the pump at any operation thereof can be read, since on the adjacent side of the wheel 29 are placed in spaced arrangeinent numerals beginning at 0, as shown in Fig. 4, whereby each full stroke of the plunger will register a gallon.

The standard l is provided upon its rear face with a lateral stop-lug 23, having' an adjustable pin 24, adapted to limit the movement of the crank 20 by contact with the lug 22 thereon when it is desired to measure out one gallon of oil, which is done by a full stroke of the plunger. To measure a half-gallon, the crank-arm is limited to a half-stroke by means of an adjustable stop-pin 42 in the lug 40 on the top of the standard l. When this pin is pushed inward across the path of the operating-crank, it limits the same to a halfstroke. VVnen a like stop-pin 41 in a similar lug on the lug 5 is adjusted across the path of the operating-crank, it will limit the same to a quarter-stroke, and the pump will deliver but one-fourth of a gallon. These pins are provided with an adjustable tap bolt or pin 43 in their heads to regulate the stroke of the crank.

In a lug 40 on the upper end and inner face of the standard 1 are fixed the upper ends of the parallel wires 38 and 39, whose lower ends are iixed in lugs 46 on the foot 2 of the standard 1. To these wires 38 and 39 are slidably secured the upper ends of the pendent parallel wires 47 and 48, respectively, to whose lower ends are secured the respective floats 49 and 50, the former being adapted to rest upon the bottom of the tank when the same is empty, while the latter is normally suspended midway of the top and bottom. On the rear face of the standard 1 and at its opposite edges are arranged graduated scales, as shown, whereby the upper end 51 of the floating wire 47 will at all times indicate the contents in gallons of the tank when it is halffull or less, while the ,upper end 52 of the Heat-wire 48 will indicate on its adjacent graduated scale the contents in gallons when the tank is more than half full.

The operation of my invention thus described is obvious and, briefly stated, is as follows: Vhen it is desired to deliver a gallon of oil from the tank, the operator rotates the actuating-crank 20 to the right relative to Fig. l until it comes into contact with the pin 24. This gives the full suction-stroke. After this he rotates the crank back to its normal position in contact with the other side of the lug 23, which gives thepressure ordelivery stroke which will deliver to the customer exactly one gallon. If a half-gallon is desired, the operator adjusts the stop-pin 42 across the path of the crank, which is then rotated a half-stroke, which upon its return stroke delivers the one-half gallon. In a like manner he adjusts the stop-pin 41 and delivers a one-quarter gallon. Vhen a customer desires to purchase an undetermined (1 uantity as, for example, thirteen cents worthmthe operator turns the operating-crank upward, as before, for the suction-stroke until the pointer 34 reaches the numeral 13 of the outer scale on the dial-plate, after which he makes the return stroke, thereby del ivering exactly thirteen cents worth of oil. Then a customer desires a receptacle of unknown capacity filled, its capacity is accurately measured by giving the operating-crank a full suction-stroke and then slowly making the return or pressure stroke until the receptacle is filed, at which time the index-pointer will register the exact value of its contents upon the inner scale of the dialplate, since at the beginning of the deliverystroke the pointer starts at Zero. Since the rotation of the drum by means of the cable 2G at each suction-stroke is to the left in Fig. 3, the pin 33 will engage the adjacent end of the pawl 32, and thereby rotate the wheel 29, which at each full stroke will register in the slot 36 an additional gallon, after which the operator returns the register-wheel to its normal position, as before described. Obviously the top 51 of the Heat-wire 47 will indicate in gallons the contents of the tank up to a predetermined limit, preferably one-haltl its capacity, after which the top 52 of the wire 4S will indicate the contents in gallons until it is full.

Having thus described my invention, what I desire to secure by Letters Patent is* l. An oil-pump consisting of an upright supporting-standard having a hollow cylindrical head havingI a short integral sleeve; a horizontal arbor rotatably mounted in' said sleeve and head and carrying upon one end a crank-arm and upon its other end an indicatorlinger for the dial; a drum iixed on the crank within the said head; a ratchet-wheel loosely IOO mounted on the said sleeve and adapted to register in gallons the liquid delivered; a pendent arm loosely mounted on the sleeve and carrying' upon its free end a pawl adapted to engage the said wheel; a lateral pin or lug on the`drum adapted to engage the said pawl to actuate the said wheel; a pump-cylimler; a vertically-reciprooating plunger in the cylinder; a cable fixed on the drum and having its ends secured to the plunger adjacent to the upper and lower ends of the standard; and a discharge-pipe connected with the pump-cylinder, all substantially as described.
